Title: High speed reciprocal and quotient computing apparatus
IPC: G06F7/62
Filed: 1969-11-28
Abstract: 1,244,239. Divider. TIME SYSTEMS CORP. 28 Nov., 1969 [29 Nov., 1968], No. 58389/69. Heading G4A. The invention relates to dividers particularly to dividers for obtaining a digital frequency value from a period. A period register 20 having a plurality of Decade Counter Units DCU contains a number representing a period. A transfer unit 30 enabled by pulses from a control Decade Unit passes the contents of the register 20 to a transfer unit 60 containing two sets of gates 1 S -8 S , 4 R -11 R . Each element of the transfer unit is coupled to a gate in each set and the gates are coupled to an accumulator 40 with gates 1 S -8 S  coupled to stages A 1 -A 8  respectively and gates 4 R -11 R  coupled to stages A 4 -A 11  respectively. The gates 1 S -8 S  are enabled by the set output of a flip-flop 80 and the gates 4 R -11 R  are enabled by the reset output. Initially flip-flop 80 is reset so that the contents of register 20 are transferred to the accumulator effectively multiplied by 1000. Nines detectors coupled to stages A 12 -A 14  of the accumulator feed an AND gate arranged to set flip-flop 8 when the most significant three digits of the accumulator are each nine. The set flip-flop causes the contents of register 20 to be transferred normally. The flip-flop also controls AND gates 90 R , 90 s  causing a pulse indicating that the contents of the register 20 have been transferred to enter either stages F 1  or F 4  of the frequency register counter so that the counter is incremented by 1 or 1000. When the accumulator is full and overflows the Control Decade Unit is stopped, and the counter contains the required quotient. The apparatus may also be used to divide by presetting the accumulator to a number such that the accumulator would overflow if the dividend was added to it, entering the divisor in the period register 20 and performing the division operation as described above.

Patent GB-622201-A (GB)
Abstract: 622,201. Condensers ; insulation. BALSBAUGH, J. C. Oct. 5, 1945, No. 25934. Drawings to Specification. [Classes 36 and 37] [Also in Group VIII] A dielectric material for a condenser is produced by assembling a plurality of layers of Alsifilm in face-to-face relationship and compressing the layers into a substantially homogeneous laminated structure. Alsifilm is formed from a gel of purified white California bentonite, which, after drying, is treated with a solution of a salt of a polyvalent cation and an organic acid, e.g. ethylene diamine diacrylate in water. The salt referred to above may be polymerizable to form a dielectric resin, in which case the treated film is dried at a temperature sufficiently low and/or for a time sufficiently short to avoid substantial polymerization. Electrode layers coated with a suitable resin, e.g. zirconyl methacrylate, are then assembled with a number of Alsifilm layers between them, and the whole subjected to a steadily increasing pressure, e.g. up to 1000 lb. per square inch, and to a temperature of 150‹ to 250‹ C., until the Alsifilm is polymerized to form an integral structure. Alternatively, the Alsifilm is cured before assembly, in which case each surface of the electrodes and the Alsifilm is brushed with a lacquer or varnish, e.g. of polyvinyl carbazole and terphenyl dissolved in toluene, the layers assembled as before, and the whole subjected to heat and pressure. In a modification, layers of Alsifilm, either cured or uncured, may be coated with a liquid dielectric, e.g. hydrocarbon transformer oil, and mechanically clamped tightly together between electrodes in a bath of the liquid dielectric. Specifications 573,759, [Group VIII], and 613,521 are referred to.

Abstract: 763,959. Cold-cathode tubes. MULLARD RADIO VALVE CO., Ltd. Dec. 21, 1954, No. 36909/54. Class 39(1). The main discharge path in a cold cathode gas-filled trigger tube passes from the cathode 1 through an aperture in a screen electrode 3 and then bends so that the mean path to the anode 2 is approximately parallel to the screen, said mean path being more than half of the total path length. The tube is connected in circuit (also described in Specification 763,960 [Group XL(c)], in which a negative pulse applied to the firing electrode 5 causes a priming discharge existing between the firing and trigger electrodes 5, 4 to initiate a discharge between the cathode 1 and trigger electrode 4, which in turn initiates the main discharge. The circuit is self extinguishing and it is arranged that at extinction the potential of the screen 3 is equal to or lower than that of the cathode 1 so that positive ions, especially those formed near the anode, travel to the screen instead of to the cathode, thus reducing the deionization time of the tube. Specification 723,892 [Group XL(c)] also is referred to.

In a fluid-pressure controller comprising a baffle-plate 20 co-operating with a discharge nozzle 24 to provide a pressure upstream of the nozzle which is related to the input control impulse applied to the baffle plate, the latter is tilted by the control impulse about an axis parallel to its surface, and the nozzle and baffle-plate are relatively rotatable about an axis at right-angles to the tilting axis of the baffle-plate. In the embodiment shown, the baffle-plate is hinged eccentrically to a diameter on a resilient hinge 19, and the nozzle 24 can be slid in a groove 22 in a circular path about an axis passing through the centre of the baffleplate. The nozzle is adjusted in position by turning the casing 34, the latter engaging a tongue 35 projecting from the nozzle; and the nozzle is held down in the groove by means of a spring 25. Pressure air supplied to the nozzle is first passed through a throttle 29, and the control pressure obtained upstream of the nozzle is taken off at 31. The control impulse is a temperature which is measured by means of a thermal element consisting of a tube 45 having a high thermal expansion and a rod 47 having a low coefficient of thermal expansion. The movement of the upper end of rod 47 is communicated to the baffle plate through a spring- pressed ball 44, the latter being housed in a screw adjusting member 39. The datum point is set by adjustment of the screw 39, and the valve to which it is adjusted is indicated by a pointer 38 which co-operates with a scale on the disc 20. A pointer 33 carried by the nozzle co-operates with a further scale on the baffle plate 20 to indicate the proportional range for the point to which the nozzle has been adjusted.
